Twitter keeps growing and they are adding another service. Today they begin rolling out Twitter Location. Users will be given the option to give some information on their location. How specific will be the call of the Twitterer.

This service is expected to be worked in over the next week. Users in 65 countries will start to see the “Add your location” link below the Tweet box.

For those of you using Foursquare and Gowalla, Twitter has worked with both services to incorporate the location features with those services. And application programmers will be able to integrate the service into their applications. So be on the lookout for some neat apps that will soon be available.
